So I thought that even if Snyder worked on a 4:3 ratio, it would still be possible to satisfyingly reframe the movie to fit a 16:9 device. So I did some test by zooming and, when needed, moving up and down some shots. This is what I obtained, and I think it works perfectly...
... mostly.
Because I have to admit that in some shots, I feet like we lose a bit of something... But maybe it's just because we have the original to compare. I mean, nothing is really cut, subject are still really readable and the shots well designed.
And then, to my surprise ...
Some shots are just impossible to crop without losing crucial informations.
What I find odd though is that those shots doesn't translate well to the 1.66:6 neither, while Snyder talked about it last summer. That was a decent format for a 16:9 screen. If it's not a thing anymore, then maybe some of those more recent shots have really been totally dedicated to the new format, with compositions that
fundamentally work vertically.
So I have to take back to what I said earlier, the movie is actually tricky to adapt properly to our home devices, at least when presented in a 4: 3 ratio.
All in all, this is not a deal-breaker for me, I guess I'll get used to it at some point but I know others are more stubborn than me, so ... we'll see!
EDIT: So I just found someone who finally tried to adapt the images being careful with the cropping. And ... It looks pretty good in motion, even the shots that I think would be too cut out. So ... I guess my post is now moot.
